MUSIC-SHEET AND TURNING DEVICE THEREFOR.

SPECIFICATION forming part of Letters Patent No. 612,672, dated October18, 1898. Application filed ly 23, 1897. Serial No. 645,687. (No model.)

To all whom it may cmwern:

Be it known that I, ALMON J. PIERCE, of New York city, in the county andState of New York, have invented a new and Improved Music-Sheet andTurning Device Therefor, of which the following is a full, clear, andexact description.

This invention relates to music-sheets, in

' connection with a turning device; and a main music thereon.

object is to adapt the music, as to the space between its bars, to theuniform rate of speed of the turning device.

I will describe my invention and then point out the novel features inthe appended claim.

Figure 1 is a front elevation of a music-turning device that may beemployed with my invention and showing a continuous sheet of Fig. 2 is asection on the line 2 2 of Fig. 1 and showing the motor as arranged forturning the music-sheet forward. Fig. 3 is a detail showing the motormechanism as reversed to return the music-sheet. Fig. 4. is a detailshowing a means for holding the reversing mechanism in position. Fig. 5is a detail showing a means for holding the rollers-in their bearings,and Fig. 6 is a perspective view showing a modification in the printingof the music-sheet.

Referring to the drawings, 1 designates a frame of any suitable materialand in which is mounted to rotate the take-up roller 2 and a feed-roller3. Affixed to one side of the frame 1 is a motor-frame i, and in thismotorframe is mounted to swing a frame 5. Having journal-bearings in tbeswinging frame 5 is a winding-shaft 6, to which one end of amotor-spring 7 is attached, the other end of said spring being attachedto a bar secured to the swinging frame5. Secured to the shaft 6 is agear-wheel 8, meshing with a gear-wheel 9, also having journal-bearingsin the swinging frame, and this gear-wheel 9 is adapted to be moved intoengagement with a pinion 10, having its shaft-bearings in themotorframe, and this pinion 1O meshes with a smaller pinion 11, whichengages with a large gear-wheel 12 on the extended shaft of the roller2. Also mounted to rotate in the swinging frame 5 is a pinion 13,engaging with the gear-Wheel 8 and designed to be moved into engagementwith a gear-wheel 1e, meshing with a pinion 15 on the shaft 16, havingbearings in the motor-frame. The speed of the motor is regulated by aweight 17 on an arm extended from an cscapement 18, engaging with aneseapement-wheel 19, on the shaft of which is a pinion 20, meshing withthe gearwheel 9. It may be desirable, however, to employ a governoroperated by a worm-wheel in order to insure noiseless action. The frame5 is mounted to swing on the winding-shaft (3 and is held in itsadjusted position by means of a lever 21, having a dog 22 for engagingin either one of a series of notches 23, formed on the edge of themotor-frame.

The frame 1 is provided with upward-inclined and outward-opening slots,the bases of which form the bearings for the journals of the roller 2,and these journals are held from outward movement by means of arms 24,pivoted to the sides of the frame and adapted to engage against theforward sides of the journals. The feed-roller 3 has at one end atrunnion, made angular in cross-section, as at 25,to engage in acorrespondingly-shaped socket in the shaft 16, and at the opposite endthis feed-roller 3 is provided with a shaft 26, movable in alongitudinal perforation in the end of the roller and held yieldingly bymeans of a spring 27 ,which engages at one end against a collar on saidtrunnion and at the other end against the roller. Obviously by movingthe roller 3 lengthwise its angular portion 25 may be moved out of therecess in the shaft 16, and then the roller, to which one end of themusic may be permanently attached, may be removed from the frame 1.

In operation when it is desired to move the music forward the swingingframe will be rocked to engage the lever 21 in the lower one of thenotches 23. I This will place the gearwheel 9 in engagement with thepinion 10, and thus the roller-2 will be rotated in the direction tocarry the music forward. hen it is desired to reverse the sheet or toreturn it to bring its first bars in line, the lever 21 must be shiftedto engage in the upper one of the notches 23, and at this time thepinion 13 will be engaged with the gear-wheel 14, thus rotating theroller 3 to return the music, as described.

It will be noted that the pinion 15 is quite small as compared with thegear-wheel 12 and that the gearing between the pinion 15 and ICO thegear-wheel 8 is so arranged that the motor will operate to return themusic to its starting-point much more rapidly than it is fed forward byits forward-moving gear. It will be further noted that a single springis employed for moving the music in both directions.

As the forward movement of the'motor is uniform as to its speed it isnecessary to so print the staves of the music-sheet as to compensate forthe relation between the speed of the motor and the time of the music.This object of my invention I carry out by variously spacing the staveson a sheet, as indicated in Figs. 1 and 6.

It will be noted that with the reversing mechanism for the motor in casea song is to be played and sung the music may be at once brought back toview when the first verse is completed, thus avoiding the necessity ofreprinting the notes for each verse.

The ends of the music-sheet may be attached to the rollers in anydesired manner. For instance, they maybe hooked onto a flap projectingfrom the roller, as each sheet of music should be provided with asuitable fastening on each end, so that if desirable several pieces ofmusic may be attached to each other and wound on the feed-roller 3before beginning to play. It may also be desirable to provide afeed-roller for each sheet of music, as when not in use the music rolledthereon will be preserved from damage and kept clean.

I have described a spring-operated motor, but it is obvious that otherforms of motor may be employedsuch, for instance, as an electricmotorwithout departing from the spirit of my invention, and in case anelectric motor is employed its driving-current may also be employed fora lamp mounted on the frame or otherwise.

The music-sheet-turning device may be inclosed in a suitable casing madeas ornamental as desired and provided with a swinging door, so that whennot in use the parts will be wholly protected from dust.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination with rollers and a motor for rotatingthe rollers at a uniform and predetermined speed, of one or more printedmusic-sheets having the time of the music prin ted thereon and thestaves differently spaced, so as to accommodate the time of the music tothe speed of the motor.
